摘要:
A species of Actinoplanes, designated Actinoplanes deccanensis Parenti, Pagani and Beretta subsp. salmoneus Huang subsp. nov., ATCC 31355, when subjected to submerged aerobic fermentation, produces a new antibiotic complex. Methods for the recovery and purification of the antibiotic complex and some of the individual antibiotic components are described.
